Though this is more like "looks like uke"
eh, most of the mangas above are uke-looking seme tho? (btw i had a whole list of that just check my lists)
check those i marked as "role reversal" http://www.mangago.me/home/mangalist/33677
i think there's plenty of uke taking seme role in the last pages.
Ok so im looking for manga that has a situation where the uke reverses and dominates the seme. Like surprise bitches! kind of thing
